摘要: The effect of Al on the structural and magnetic properties Pr3(Fe1−xAlx)27.5Ti1.5 (x=0.1, 0.2, 0.3) compounds has been investigated by x-ray-diffraction, magnetization, Curie temperature measurements. All these have formed in monoclinic symmetry with A2∕m space group Pr(Fe,Ti)12 as secondary phase traces α-Fe. monotonic decreases MS both at 300 80K are discussed basis electron transfer from 3p band to 3d Fe near EF. variations TC explained using Friedel approach. In all compounds, easy magnetization direction is away b axis.
